I just built my robot I started programming "Moving Forward" and when I tried to compile and download the program a new window has appeared asked for selecting communication port for paltforms. I have selected the automatic selection but it doe not work. I tried VEX USB port (status: busy) but it also does not work. I'm not able to select any port. What should I do please help.

Re: problem with selecting communication port for paltforms

Double check to make sure that the VEX IQ Firmware Update Utility is not running in the background (http://www.vexrobotics.com/vexiq/software/firmware) as the IQ (like most other microcontrollers) is only able to communicate with one program at a time. Also, try rebooting the IQ brain and restarting ROBOTC (after closing the Firmware Update Utility, if it is open) to reestablish the communication link between the IQ brain and ROBOTC.
